Design And Application Of Online Monitor System In A Cold-rolling Continuous Annealing Line

A cold-rolling continuous annealing lines combines cleaning,annealing,striping and fine striping of steel belt,which has been used widely.Compared with bell type continuous annealing furnace,its advantages including high productivity,production diversification,high quality and low price.Continuous annealing technology has been developed rapidly.Moreover,production cycle can be squeezed intense.Online monitor can void accidents effectively.Maintenance can hold all running information of the equip in order to reducing the halting time.Run-to-breakdown maintenance has been replaced by preventive maintenance little by little.Process route and components of cold-rolling continuous annealing line has been introduced.Then the history of equipment status monitor and fault diagnosis technology is showed briefly.Based on the basic concept of equipment monitoring and fault diagnosis,the fault types and typical spectrum of the continuous annealing equipment are analyzed.Online status monitor system is consist of vibration monitor system and temperature monitor system.This system has three levels topology network structure.Each level of network is isolated and interactive.Staff can monitor the status of key connect in the line,which can avoid a terrible accident.Bearing status long-distance monitor system transmit information.of temperature by the way of wireless.This system has a low-power,reliable,extendibility,low price,easy to maintenance.The examples shows,this monitor system can reflect field situation.This is first-hand data,which can be supplied to maintain.Everything goes well because of the temperature transmit information.Online status monitor system can help staff to monitor to know the key components.It can void accidents effectively.Total investment will be paid back after about three year.
